Best PED for cardio endurance

As a member said earlier AAS will effect your endurance mostly by allowing you to recover faster from more training than you naturally could.
Without it you might recover from 4 sessions per week and with AAS you might recover from 6.
So its a huge deal in the long run.
In my experience the right dose is the one you can manage without getting side effects.
There are other medications that raise RBC count beside EPO tennis players are getting popped for Roxadustat might be interesting.
Also one important factor for AAS is recovery between round if thats the kind of sport you are in.
I've always considered most PEDs to be recovery-enhancing drugs rather than enhancing performance directly, including AAS. The idea being that PEDs allow athletes to train harder and train more frequently than a non-PED user. So obviously the athlete who trains more intense/frequently is going to improve to a greater/faster degree, all things being equal.

And good point that isn't emphasized enough is what does "endurance" mean to different people. This is unavoidably related to the kind of sport you are in.

Improving endurance to a 250-lb bodybuilder means something entirely different to improving endurance for a 180-lb runner seeking to improve his 10k times. It's a fundamentally different questions with different goals that has different answers depending to the sport-specific goals.

We often overlook this. Or assume that everyone asking the question has similar goals to us since this has always primarily been a forum populated by mostly bodybuilders/powerlifters/other strength atletes.
 
Realistically, wasn’t Tbol literally made for this? The only purposeful PED?

I found that Tbol gave me near unlimited energy.
I used to think that. But it, like most every AAS in the 1950s and 1960s were created for medical therapeutic indications. The so-called "golden age" of steroids was an interesting period were society and the medical community didn't demonize AAS but genuinely and optimistically thought they could be created and used to cure many legitimate medical conditions.

Oral Turinabol just happened to be one such AAS that was manufactured exclusively in Germany in the 1960s.

In practice, though, peds do directly improve your performance irrespective of training. The perfect example of this is blood doping. It is literally endurance in a bag. Another example are stimulants like amphetamines/methylphenidate. These drugs work immediately.

I agree with you about specifying goals, though. But I think it's reasonable to make certain assumptions when someone mentions endurance and epo in the same post. I've never confused a bodybuilder for an endurance athlete.
 
In my opinion and experience it would be masteron.
It shed all the excessive water off me, is a potent erythropoietic agent (means rbc increase), for fighters that are depending on cardio and strength it also is optimal as i capable of increasing neural drive (strength).
One of the biggest positives for me but probably not for a lot of bodybuilders was that it didnt cause a massive pump for me, rather caused a worse one and kept me flat, which resulted in this not hindering my ability to endure longer sparring sessions and runs.

Tbol, which got named often in this thread caused terrible lower back and shin/calf pumps for me and eq was similar to mast yet caused the same pumps as tbol.

The only other that comes to my mind is winstrol, which helped with my cardio but this is still depending on the users response to winstrols possible joint pain.

I'm always careful to qualify my statements. I agree with those examples especially amphetamines, Any drug that you can consume and instantly improve performance seems to be more of an anti-doping issue than those PEDs that are primarily recovery drugs. It seems like the penalties would reflect that but they don't.
 
I have done and do a lot of high level athletic training which requires a lot of cardiovascular endurance and only thing I truly noticed that helped was TRT levels of test.

Tbol maybe works but I get such god awful shin pumps I cannot function athletically.
 
It's probably controversial to say this, but amphetamines are my favorite performance enhancers when it comes to endurance. Actually, I believe they increase performance in all areas.........and they do that better than anything I can think of. There is an increase in physical capacity, but the largest part of the positive effect is the increased mental endurance.

It's not as easy as taking a pill and then you become a super endurance athlete. You really have to have a tolerance for amphetamines and know your body well enough so that you don't burn out. This is where you need to really know your nutrition and supplementation and be proactive in your recovery and preventing burnout. But you can stack so many long training sessions that when it comes to the real event, you will have developed true mental endurance.

The best way to try this is to basically use Vyvanse every day for a period of time (the longer the better) and train. But you have to be very tolerant to the substance or else it can be too intense and that will work against you.
 
I don't think any supraphysiologic dosage (or T equivalent) of AAS will directly help endurance.

People will steer you towards AAS that are thought to be more powerful stimulators of erythropoiesis than others. The idea is that these will stimulate hematocrit and your endurance will improve.

Well, erythropoiesis is one effect of AAS that may help but pretty much every other side effect of supraphysiologic AAS use will compromise endurance.

So if you do benefit significantly -- let's say from a 12-week cycle of equipoise -- you won't reap the benefits of increased hematocrit until well after the end of the cycle. And even then, you may only benefit if you lose the weight you gained from the 12-week equipoise cycle.
I have had issues with increased rbc and low iron and finding the right balance when on blasts. It also takes me longer than normal to replenish iron after giving blood.
I was curious about your comment on if EQ did help endurance it would likely be at then end of a cycle. Is this only because of the weight you would drop being off cycle?
I have heard that the new rbcs take a decent amount time to saturate with iron and hemoglobin/oxygen and I was wondering if this could also be a contributor to your statement. For me as well, there have been instances where yes, I do have extra rbcs but several are misshapen and/or smaller than they should be.
Im no expert just generally curious what you or anyone else with some intel thinks.
Thanks for any info.
 
Extra weight kills endurance/cardio capacity. It’s less effort for your body’s systems to move 190lbs than it is to move 210lbs at the same speed/distance

Body weight is one obvious variable that usually changes after discontinuation. But I suspect, and this is my own speculation, is that supraphysiologic levels of AAS has negative impact on some cardiopulmonary parameters influencing endurance performance. It seems that high levels have a negative impact even before bodyweight increases on a cycle.

And yes, I think any androgen-induced erythropoietic effect would enhance performance in the long-term following AAS cessation and return to normal/baseline CP parameters (and bodyweight). It's just not the most efficient way to do so and compromises performance while on cycle.
 
Mots-c made a huge difference for me, but did cause some insomnia.
Gw0742, small but noticeable improvement, but most-c was much more noticeable.

Another to investigate that hasn’t been mentioned yet would be aircar
 
EPO, but from my experience the stack of winny stormba 20 + var 25 and a muscle relaxant which is not addictive named l’iodé sap baclofen At 60 mg omg I did 1h30 cycling before training, did My max pr at the every session, then after 6 months it faded out but the combo was insane , you feel no muscle pain and no joint pain with baclofen and at high doses it’s stimulant when you start doing something it activates you like crazy, it’s used a lot in cycling and cross fit because of its properties
 
I’ve ran all 3 of the compounds mentioned. Eq, tbol, and cardarine. Cardarine gave me a significant boost when I took it an hour before I worked out. I felt like I didn’t get winded as fast and I could do cardio longer. It’s a ppar delta agonist so it’s allowing more energy metabolism in the cells.i stopped taking it because the studies they did with the rats freaked me out about cardarine causing cancer. EQ takes about 6-8 weeks to peak in your bloodstream, so unless you are planning on running a very long cycle, you won’t notice those affects until later on. I love tbol, I had a very good test tbol run and I felt amazing, I could absolutely crush my hit workouts and it starts working fast. I would choose between cardarine or tbol if I were you.

Off topic a Little sorry Buț it ca-n help OP too: Just started my first run of tbol at 20 per day, you find it works best by injection or sublingual? Or it’s bs and I just have to swallow it? I read the metabolites of tbol gives the sides for some ppl like kidney stones

I take it since 6 days and I felt more happy at first then now I feel a bit lethargic after I take it. When it kicks in how is the headspace? I find myself more endurant already and I have micro ups during the day like it’s starting doing something (I run it with test 300, mast 490, mesterolone 50, Dbol 20, it’s my first time I use it and I find it a bit nootropic, im insomniac like in tren train and not sore after training but I know it didn’t kicked in yet.. it’s something different than what I used in the past)

I had it in the oral version. Never used inj or subq. I ran it at 50 a day. This was from alpha pharm which in my opinion is some of the best, expensive as shit though. I’ve had bunk tbol before. I only ran it for 6 weeks max. Are you sure it’s the tbol causing Those issues or some of the other compounds. Or combo of all of them.
 
Rbc increase

You’ll get that from winstrol as well. Plus the strength. And it won’t turn you into a water buffalo , a concern if you need to make weight.

Can’t run it for long , that’s the downside. The liver toxicity.


Or primo ? It was also indicated to treat anemia
